Usage

Oral Care & Anti-Caries Toothpastes (Core Absolute Application): Serves as the global standard active anti-cavity agent and enamel remineralizer integrated into toothpastes, mouthwashes, and dental gels.
- Mechanism & Enamel Protection: Upon dissolving in saliva, it releases monofluorophosphate ions that promote tooth remineralization. These ions convert hydroxyapatite in the enamel into acid-resistant fluorapatite, significantly enhancing the teeth’s resistance to acid erosion and inhibiting tooth decay.
- Abrasive Compatibility: Unlike conventional fluoride sources, sodium monofluorophosphate is highly compatible with the calcium-based abrasives commonly used in toothpaste; it does not readily form insoluble calcium fluoride precipitates that would render the fluoride ineffective.
Pharmaceuticals & Osteoporosis Therapy: Formulated into therapeutic agents intended to increase bone mineral density and treat osteoporosis.
Industrial Corrosion Inhibition: Applied as a concrete corrosion inhibitor to protect steel rebar within structural concrete matrices, and as a metal surface treatment agent.

Storage

Must be stored in a cool, dry, and well-ventilated dedicated warehouse.

Keep away from heat sources and open flames; suggested storage temperatures should not exceed 30°C.

Keep containers hermetically sealed and sheltered from atmospheric humidity.

Strictly avoid joint storage alongside mineral acids or alkalis.
